I am personally rather indifferent to the whole GW/AGW affair. That said, it's just silly to infer that extra snow means the globe isn't warming. For example, consider: if 100 billion tons of ice melts at the poles, and global snow levels then increase, in winter, when was the water cooler: 1) when it spent all year round being ice, or 2) when it spends 4 months a year as ice? If you guessed #1, you'd be right.
Of course, I can ask the question a different way, and just make you mental. If the globe is warming, and the average temperature goes up, would it be possible for the increased water vapor as it traveled across the poles to actually generate an expanding ice sheet? If you agreed that it was possible, you'd be right.
Now the part that will make you mental is that these two questions imply answers that could be superficially viewed as contradictory. I'm fun at a party, eh?

In my mind it's all about confirmation bias. Which is to say, when confronted with a larger list of facts to assess, human beings have a remarkable ability to select only a small subset of the facts and use those to confirm their beliefs. I encountered this last year. I will relay the anecdote.
Sometime last year a study came out that "proved" that caffeine drinkers who regularly drink caffeine induce no practical effect to themselves, and only restore themselves to what would be a baseline level. Over a twenty year period I have read summaries on many, many caffeine studies. This particular study stood alone as an outlier in a much larger field of study. I noted this with amusement and went on with my life.
One day not so long later, I was getting coffee at work. A coworker of mine intruded to attempt to tell me about the study. I cut him off cold, and was quite irritated. This coworker was Mormon. I did not need to mire in the narrowly minded comfort-confirmed mentality of someone who is able to learn nothing else. It's just sad, really.
Of course on the subject of global warming, the issue is political. I once heard a great definition of politics, once: "politics is who gets what". It's true. While politics is about many things, it's certainly about resource allocation, and when you consider it from that perspective, and decide to tolerate the notion that for human beings resource allocation will always be highly contentious, what you will do is become a bit jaded like me, which is to say, unsurprised, disdainful, and accepting of the ugliness of politics all at the same time.

Energy levels (not temperature) have increased dramatically in a rather short time and the climate is trying to find a place for all that extra energy now. So the oceans are cycling rapidly (Nina/Nino phases), precipitation levels etc are changing. In essence we're cycling rapidly between extremes. Anecdotally in Utah, last year we had the largest snows on record, and this year is probably the driest on record. For my entire childhood (I'm nearly 40) these cycles were nearly a decade long now they are a cycling in a year.
This will probably continue for a decade or three as the system tries to stabilize the energy levels and sink some of the temperature increase into the oceans, etc. The models aren't perfect and the deniers point to that, but the reality is we simply don't know how the climate will stabilize these energy levels, we can only make predictions based on previous climates we have rudimentary knowledge of. I'll likely be dead long before the worst of climate change hits (major shifts in breadbasket areas), but I know I'm going to live during the most erratic climate change this world's ever seen.
The scariest part to me is how to plan for the future because there is one thing the models do predict and that's the bad weather (the kind that kills people) is going to increase dramatically. I was hoping the SW would get wetter as the models predict but it appears, at least during my lifetime, things are just going to get more erratic making it very difficult to predict and manage scarce water resources.
The funniest part about Climate Change and the Deniers is that the government is planning for it. The military and defense planners and many others are planning for summers where the Arctic passage that's never existed becomes a reality. And before people say this is because of Obama I'll point out this planning started under GW Bush. Those in the know and with power and influence are causing our government to react like Climate change is not only a reality but something that's very important strategically including how to get to all that oil that's in the arctic that no one ever thought would be accessible. This includes a certain pair of brothers that are highly invested in carbon based energy and fund much if not all of the deniers making plans to drill and tap that oil when the ice melts permanently.

I find that snow is more likely to fall closer to the freezing point, in fact the temperature generally rises when it snows.
Basically what I am saying is it can get too cold to snow (well not really but the probability the conditions for snow are vastly reduced), below 0F you really don't get much precipitation. Snow requires a few things to occur before you see those white flakes. 1 Moisture saturation, the more moisture in the air means the higher probability of snow, 2. Temperature, must allow the ice crystals to stay frozen on their way down, 3 a temperature difference between the lower atmosphere and the area where snow develops. On really cold days there is not enough heat to drive the saturated air to the very cold layers of the atmosphere where snow forms
Oh wait you said I was wrong? Hmm guess not.

Being from Wisconsin, I have to agree that the warmer winters tend to have the most snow. Cold winters tend to have the most accumulation while warmer winters tend to have the most precipitation. Once you get below 10f, the chance of snow drops dramatically. Below 0f will give you a very clear sky and snow almost never falls when the temp is below 0f.
The biggest snow storms tend to happen around 30f-34f.

That is *exactly* the case, but we're talking about temperatures at the point where the phase change occurs, not the local weather.
Water evaporates faster the warmer it is - warm air heats the surface and speeds the process. Warmer air can also hold more water as water vapor, which is why 70% humidity in the dead of winter is actually still fairly dry air while 70% humidity during a heat wave is oppressively wet.
Clouds form when a body of that warm, moist air (a warm front) collides with a body of cold air

Except snow doesn't form down here, it forms high up in the atmosphere, to get that water up there you have to have heat to drive the saturated air up. Notice it snows far heavier on the warmer winter days. Once the temp drops well below freezing the chances of snow are greatly reduced.

Ok read your article. It seems the primary reason for the increased ice in the Bering sea as compared the rest of the arctic, which has seen a decline in sea ice coverage, was due to winds blowing the ice down to the Bering strait where it backed up until the ice wall finally collapsed and the ice then flowed into the Bering sea while the low temperatures helped keep it frozen.
Not sure what point you are trying to make with it, as it even mentions the record highs in the continental US.

How is it inconvenient for the pro-science group? The increased snowfall (and the warmth of the contiguous states) has a known cause - the change in the jet stream. And the change in the jet stream has a known cause - a change in the arctic oscillation. And climate theory indicates that one of the things that happens when you lose the summer arctic ice cover is that the arctic oscillation changes. And what has been causing the summer arctic ice cover to disappear? Global warming. So, while this doesn'

Enough cooler, apparently, to more than balance out the relatively local heat we've seen in the US, which is caused by a regional weather situation that's also apparently starting to change.
2011 was the ninth warmest year on record despite the cooling influences of La Nina. What period are you taking your trend off? The last three-four years?

Actually, La Nina years do depress the global atmosphere average temperature by pushing heat down into the ocean. El Nino years do the opposite, they pull heat up from the oceans and increase global average temperature. The effect is small (about 0.04C for each) but when El Nino and La Nina conditions are taken into account, it creates a much clearer picture of the earth's warming trends [skepticalscience.com].

Let's compare all those highly-accurate satellite temperature measurements with the satellite data from only 200 years ago when Ben Franklin lofted the first earth observing satellite.... oh, wait, ....nope.... I guess we have no such data. Oh, alright, lets use the highly-calibrated thermometer data from way back 200 years ago when some sea captain measured the temperature somewhere (plus or minus 200 miles from a point in the mid-Atlantic) using his very accurate mercury thermometer that was carefully calibrated to the NIST standards.... oh, wait, nope.... no such traceable calibration and the candle-light made reading that thermometer within 1/10th of a degree relative to a scratch in the brass frame a bit tough.... not to mention that the guy was tired and did not see any reason to worry too much about being too precise...
That was not working too well... let's use the hyper-accurate temperature measuring device all Americans prefer to use when they can afford it: tree rings. Yes, a thermometer from 200 years ago has a few calibration issues and the satellites were not very good 200 years ago, but everybody who believes in science knows that a tree ring or some muck from the bottom of a river is accurate to within 1% of a degree! Why, I for one, chop down a tree and check the tree rings for every morning....why bother with a thermometer when an axe and a precise temperature tree are available?
All the hype about "record" and "all-time" high or low temp data is manipulative and speculative. There were no humans (not scientists, nor even amateurs) taking and recording temperature data on 80% of the North American continent before 300 years ago, and the planet is at least 6000 years old (Grin) so we are statistically blind to most of the temperatures for world history. If you plug-in the actual age of the Earth, you know that we know, with calibrated precision, next to nothing about the long-term "global temperature". Comparing data from highly-accurate, calibrated and traceable, modern scientific instruments to creative and imaginative speculation about past temperatures is extremely dishonest and anti-science, but a great way to write a paper and get more taxpayer funds for another year of "research", which beats the hell out of flipping burgers
I'm no luddite... I used to design and build scientific instruments and now work in aerospace, but I am outraged but the so-called scientific climate studies that are done by people who have (and I will be charitable here) apparently forgotten some of the most-basic rules of science in order to score political points or stay popular with their peers. Rules like:
1. Different data sets measured two different ways with two different types of instrument cannot be honestly compared without a common calibration.
2. Data collected with two identical instruments still cannot be compared if one of them lacks traceable calibration
3. You can never gain absolute precision by using additional imprecise data. (in other words: if you sum-average or in other ways lump-together a bunch of data that is accurate to 1 percent, you may get a more-precise idea of what your imprecise measuring device thought it saw, but you have absolutely not obtained a better-than 1 percent measurement of what was actually there... and such data manglng actually reduces absolute precision)
They used to teach this stuff in first-year science classes several decades ago...

You are a luddite when it comes to climate science. Or science in general since your arguments wouldn't even stand up to the most basic scrutiny of a peer-review.
How about you take your clearly superior intelligence and read up on the subject. You can start with the IPCC report which explains the research very well in laymen's terms. After that, you can read the thousands of referenced scientific papers on the subject.
Or if that's too much, you could go ahead and write a paper without doing any background research that explains the current observations without using AGW. Submit it and win a Nobel (assuming your paper doesn't get absolutely destroyed for the child-like logic you use here). That's a cool million for you right there for the taking. Easy as pie.
Global warming isn't some new theory someone pulled out of their ass a couple years ago. It's over 120 years old. Scientists have been predicting a warming world due to increases in greenhouse gases since before the computer was invented. So if you can come up with a plausible theory that explains how all the current science was built on nonsense you'd be the scientific equivalent of Einstein.

Many, many fake skeptics have questioned the positioning of the sensors. In fact, some have put together a study of that and the data they found was that there was a problem with the sensors - there was a slight bias to underreport the warming. It wasn't for all the sensors and it wasn't a large amount, but it showed that the sensors did not make things seem warmer than they really are. In addition, a number of studies have shown that the positioning of the sensors isn't really affecting the trends. In

As your link says, we have ice-core data [wikipedia.org] going back up to about 750,000 years. This gives CO2 and temperature readings for the last 8 ice ages. Over this period CO2 has varied between about 180 and 300 ppm [wikipedia.org].
Currently, CO2 is at about 390 ppm [wikipedia.org], significantly higher than at any point in at least the last 750,000 years. Since CO2 drives temperature, we can expect global temperatures to rise to higher than at any point in the last 750,000 years.

Here's a nice movie from the NASA CO2 satellite:

You can see that global CO2 levels rise fairly evenly, with Antarctica only lagging the Northern Hemisphere by a few years. Over the time scales involved in the ice cores this lag would be invisible. Also note the scale: it's 360 to 390 ppm, so although the colours look dramatic, the differences being shown are mostly less than 10% of the total and roughly equal to the annual variation.

Your assumption would be incorrect. Natural variability means that short term temperature variations occur. A true measure of the temperature of the Earth would look not only at atmospheric temperatures but ocean temperatures as well (and even land temperatures). On average about 90% of the warming that occurs each year goes into the oceans. But cycles such as El Nino/La Nina cause large transfers of energy between the oceans and the atmosphere so in the short term the atmosphere can cool. A recent sta
